[cobalt-users] RAQ2->RAQ3(?) Backup Server

[webmaster <webmaster@xxxxxxxxx>]

I've been asked to set up an Intel processor-based application on a Linux
machine as a backup to a white-box (RH7) we have running (just in case).  I
had the brilliant idea of using a RAQ3/4 as the backup, and making it do
double-duty as a backup for our RAQ2 e-mail server.

Doable?  Is it possible to use the CMU to copy/migrate (stupid semantics)
the user accounts (and associated files) from the RAQ2 to the RAQ3 on a
scheduled basis, then, if the RAQ2 ever pukes its guts, just automagically
turn on the RAQ3 to provide the e-mail services our customers have become
addicted to?

Am I better off getting another RAQ2 for our mail server backup and using
another white box for my other application?

Any other ideas/concerns/caveats/warnings?

Thanks,
Andy
